BOARD PRY Eldon L. Krieg, South Whitley, Ind.

Application October 3, 1945, Serial No. 619,955

7 Claims. (01. 254131) My invention relates broadly to tools and moreparticularly to a construction of tool for removing boards or sidingfrom studding or rafters with minimum injury to the boards forpreserving the boards for reuse.

One of the objects of my invention is to provide a simplifiedconstruction of tool which may be used as a pry in removing boards orsiding from studding or rafters without splitting or injuring the boardsand thus preserving the boards for reuse."

Another object of myinvention is to provide a construction of toolhaving lug projecting members connected to a bodystructure and which maybe manipulated in positions between studding and boards of sidingthereon for quickly and easily removing the boards or siding from thestudding. l

Still another object of my invention is to provide a construction oftool consisting of a tubular body structure and integrally connectedlugs extending-in planes substantially normal to each other and havingmeans for engaging studding in oneplane andtheboards or siding which isattached thereto in'another plane for exerting through leverageipressureforces for removing the boards or siding from the studding whilepreserving the boards or siding against damage for enabling reuse ofsuchboards or sliding.

Other and furtherobjects of my invention are the production of a simpletool serving as a board pry as set' forth more fully in thespecification hereinafter following by reference to the accompanyingdrawings in which: i

Figure 1 is a perspective view of a board my tool emb'odyingmy inventionandshowing the tool in'position for removing a board fro m a studding orrafter; Fig. 2 is a side elevational view of the tool of my invention;Fig. 3 is a horizontal sectional view taken on line 3-3 of Fig. 2; Fig;4

is an end view of the board pry looking in the and used. asa pry forremoving boards or-siding from studding or rafters without splitting orinjuring the boards more quickly and easily than by the use of ordinaryhammers or pry bars for preserving the boards for reuse. I provide atool formed from a tubular bodystructure having lugs 2 integrallyconnected therewith andextending in planes substantially at right anglesto each other, the shape of the tool being such that one set of lugs maybe engaged with respect to the studding while an applicator pivotallymounted on the normally arranged lug or lugs may be applied against thesurface of the board'associated with the studding and which is tobe'removed Without injury. The applicator for engaging the board to beremoved may be constructed in various forms such as for example a pairof pivotally mounted applicator members symmetrically journaled onopposite sides of a lug projecting from the tubular body structure ofthe tool or a single applicator member journaled between a pair of lugsprojecting from the body structure of the tool and associated in eitherarrangement with lugs extending substantially normal to the plane of theaforementioned lugs and integrally related to the body structure of thetool and serving as a fulcrum member with respect to the studding fromwhich the boards are to beremoved. By reason of the symmetricalconstruction of the board pry of my invention it is possible to use theboard pry either to the right or the left of studding and/or to applyleverage to the board structure of the tool either inside or outside ofthe building of which the studding and attached boards forms part of thebuilding structure. I have used the tool of my invention as describedherein with very satisfactory results and while I have shown the tool incertain preferred forms I realize that changes in design may be made andI intend the structure shown herein to be regarded in the illustrativesense and not inythe limiting sense as I desire to include allsuchmodified forms within the scope of my invention.

Referring to the drawings in detail reference character I designates atubular body structure forming part of the tool of my invention. Thetubular body structure I has a pair of transverse- 1y extending lugs 2and 3 weldedor otherwise integrally connected with the tubular bodystructure 1 adjacent the end of the body structure. Adjacent theopposite end of the tubular structure l I provide an arm for extendingin a plane substantially normal to the plane of the transverselyextending lugs 2 and 3 and welded orintegrally connected with thetubular body structure l. The arm 4 is curved in a direction toward theend of the tubular body structure lwhich includes the integrallyconnected lugs 2 and 3 and terminates in a position spaced from thetubular body structure I. The end of the arm it; serves as a journalingmeans for theapplicatcr members or pressure feet and B which arejournaled arm 4. The pressure feet 5 and 6 are symmetrie cally formedand are balanced to pivot about the center formed by pivot pin I and areeach formed with a straight edge 5a and 6a and rear curved edges 5b and6b. The length of the pressure feet 5 and 6 is such that they clearthedistance be'-:-

tween the center of pivot pin 1 and the surface of the tubular bodystructure I thereby permit--- ting the pressure feet to be angularlyadjusted to' 'that position in-wh'ich the board pry may progressivelyfunction most'easily in the process of applying pressure against theunder surface oi board 8 forremovingthe board from nailed positi-ohwitl'f resp'ect'to studding or joist 9.'

NhandIe bar I El -is inserted into the interior oftubular-"bodystructure I when the board pry is to b'e olderatedfromtheinside of the building structure; If the board'pry is to be operatedfrom tl'ie outsideof'the building structure, the handle 'bar isremoved-from the position It] andutilized inthe po'sition II' on theoutside of the building structure? The handle may be slid through theinteriorof the'tubular body structure I to protrudeon either end thereofdepending on which side OFtheboardS andstudding the'tool is used.

The h'andle bar is secured or locked in a desired selcted'position forobtaining the required leverageby means of the thumbscrew represented atl2? The'liigsi and 3"which are engaged against the rafters or' studdingproject on opposite sides of the tubularbodystruoture l and are providedwith straightedge'engagingfaces 2a and 3a and curved rear"edges 2b and3b, permitting the tool t'ti' b'e' inserted-"in a minimum of 'space'iorobtaining'*th'e--required fulcrum on either the left or right h'andsidofthe rafter; studdi'ng or joist 9.

Ifi'a'modi'fied form of my invention I may'providtl'ie pry with a pa rof projecting arms M and |5 insteadofasingle arm 4 for embracingoppositesidsof'a' single pressure foot l'a instead of a 'p'air'ofressure feet 5 and 6 as heretofore ex lained The single pressure foot 16is journale'd at 'l'Finthe two' arms [4 and [5. This arrangement 'may besimpler to o erate under certain"-condi'tions as the width of thepressure applicator'isIeSsinthe arrangement shown in Fig.-6'-"than"thearrangement illustrated in Fig. 5 and thereerefin tances inwhich it is necessary to worhu'nder extremely confining positions wherespacel mitations are very severe.

Intheuee-ofthe tool of my invention an initial or'-'topb'oard"isgenerally removed by hand or'by the usual m'eans to expose the studding.Then, tomemove"thesuccessive boards from a position inside the studdingor the building; lug 2 can be lioolfed onthe outer sideof the studdingQand tlie"pressure-'fe"et 5 and '6 may be placed "againsttlieinsi-deoftheboard- B'which is nailed to joist Qandthena" downwardpressure exerted on the Handle bar l0-'to'-develop the required leveragefor-forcing -the board 8 outwardly away from the studdi'ngfl" Toremove-the board's 8 from the studding from a position outside of thebuilding structure the handle bar is inserted in the tubular structure Iin the position [I with the end of the handle bar protruding outside ofthe building. An upward pressure is then exerted on the bar I l to prythe boards 8 off of the studding 9.

The action of the tool is such that the boards may be pried oiT of thestudding or rafters without splitting or damaging the boards; this maybe accomplishedemore easily; and lgrapidly than by theusu'almeans; thussaving both material and labor; and the tool of my invention is capableof manufacture and production on a mass scale atlow cost.

While I described the tool of my invention in certainof itspreferredembodiments I desire that itbe unders'tood-that no limitations upon myinvention are intended and that modifications may be' made within thescope of the appended claims without departing from the principles of myinventionza,
